BALlNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 627,460, dated June 20,1899. Application filed May 18,1893. Serial No. 681,093. (N0 model.)

To all whom it may concern.-

Be' it known that 1, JOHN HEAsToN, of Nashville, county of Davidson, andState of Tennessee, have invented a new and useful Improvement inBaling-Presses, of which the following is a specification. y

This invention relates to pressesdesigned for baling hay or othermaterials, and has reference more particularly to that type of pressesembodying a baling-trunk, areciproeating plunger, and a rotary sweepoperatively connected to the plunger.

The invention consists in various improvements in presses of thischaracter, having in view simplicity and durability of construction andeffectiveness in operation.

The invention also consists in the details of construction andcombination of parts, hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of myimproved press. Fig. 2 is a top plan view of the same. Fig. 3 is avertical longitudinahsectional elevation of' the baling end of the presson an enlarged scale. Fig. 4 is a similar view showing the parts in adifferent position. Fig. 5 is ahorizontal sectional elevation of thepower end of the press, on an enlarged scale, on the line a a of Fig. 1,the parts being in the position they occupy when the plunger is in theposition shown in Fig. 4:. Fig. 6 is a View similar to Fig. 4:, with theplunger at the end of. its stroke. Fig. 7 isa view similar to Fig. 5,with the parts in the position they occupy when the plunger is intheposition shown in Fig. 6.

Referring to the drawings, 1 represents a trunk or baling-chamberprovided, as usual, with an opening in its top for the introduction ofthe material to be baled. It is sustained by a bolster 2, which in turnrests in an axle 3, on which are mounted groundwheels 4.

5 represents a plunger mounted to reciprocate within the trunk, as morefully described hereinafter.

6 represents the power or forward end of the press, comprising a sweep7, a roller-arm 8, operated thereby,and a cam-arm 9,0perated by theroller-arm and adapted to give motion to the plunger through the mediumof a drawrod 10. These parts are mounted on the forward end of acoupling-beam 11, sustained by ground-wheels 12 and extending rearwardalong the under side of the trunk beyond the bolster and over the axle,it being detachably connected to the bolster by means of an angle-plate13, fixed to the upper side of the coupling-beam and connected to thebolster by a horizontal removable coupling-bolt 14. This constructionadmits of the shortening of the press for transportation over the field,it being but necessary to remove the coupling bolt and disconnect thedraw-rod and'push the power end toward the trunk, the coupling-beamsliding over the axle and extending along the under side of the trunk.

The plunger is formed with a vertical pressure-face 15 and beyond andforward of the face with a vertical slot, through which is extended atthe front end of the plunger a horizontal rod 16, and on this rod aremounted the front ends of two links 17, the rear ends of which arejointed to one end of an angular rocking lever 18, comprising a frontarm 19 and a rear arm 20, the links being connected at their rear endsto the arm 19. The rocking lever is mounted at its angle on a horizontalrock-shaft 21, journaled on the under side of ing lever is connected bya link 22 to the rear end of the draw-rod 10 before alluded to. Therelative arrangement of these parts and the form of the rocking .leverare such that when the plunger is at the beginning of its stroke, asshown in Fig. 3, the links 17 and the arm 19 of the rocking lever willextend ina substantially straight line, with the link 22 extendingalongside of the arm 20 and the draw-rod at the rear end of its movementand extending closely along the top of the coupling-beam. If now thedraw-rod is moved forward to the position shown in Fig. 4:, the rockinglever turning on its axis its arm 19 will be moved rearward and by meansof the connecting-links 17 will move the plunger rearward toward thedischarge end of the trunk. At the same time the arm 20 of the rockinglever will be moved downward and forward, the coupling-beam at thispoint being recessed vertically, as at 23, so as not to interfere withthe movement of the press. In this position of the parts the plunger hasnearly completed its stroke, while the drawrod has made buthalf itsmovement. On the the trunk, and the other arm 20 of the rockplungerfurtherand remaining movement of the drawrod to the position shown inFig. 6 the plunger will be caused to finish its stroke, which at thispoint will be far less in proportion to the movement of the draw-rodthan was its first main movement. The result of this is that the firstpart of the stroke of the plunger will be rapid, while the last part ofthe strokethat where the resistance of the compressed mass isgreatest-will be proportionately slower. In connection with this actionof the plunger the power mechanism is so constructed that the eifect isaugmentedthat is to say, the draw-rod is moved slower at the beginningof the stroke of the plunger and less power is required to finish thestroke, owing to the increase of leverage 011 the cam-arm, as will'nowbe described.

The roller-arm 8 consists of a flat plate having friction-rollers 24:and 25, respectively, on its end 011 the under side, and it is fixed toa vertical shaft 26, mounted in bearings in the coupling-beam, andbracket-plate 27, overlying the forward end of the beam and sustained byvertical overhanging brackets 28, rising from the beam. The roller-armis situated between the bracket-plate and beam and receives a rotarymotion from the sweep 7, which is fixed to the upper end of the shaftabove the bracket-plate. The cam-plate 9 is pivoted at its inner end ona vertical axis 29, situated a short distance longitudinally in rear ofthe shaft 26, and the plate is formed with a vertical cam-rib 30,terminating at its extremityin a rounded end, as 31. This camsurface isadapted to be engaged by the rollers, as shown in Fig. 5, the rollersdisengaging the cam-surface at about the point where the circular pathsof the rollers and the end of the cam-rib coincide, as shown in Fig. 7.IVhen the plunger'is in the position shown in Fig. 1, the draw-rod is atthe end of its rearward movement, with the cam-arm extending rearward,as seen in Fig. 2. On the rotation of the sweep in the direction of thearrowin Fig. 2 the roller 24 on the end of the roller-arm will engagethe cam-rib at about midway of its length, and on the continued movementof the sweep the roller will move along the cam-rib toward its outer endto the position shown in Fig. 5, thus gradually approaching the point ofconnection of the draw-rod and cam-arm and proportionately increasingthe leverage on the arm and proportionately reducing its speed ofmovement. On the further movement of the sweep the cam -arm will becarried around to the position shown in Fig. 7, at which point thecircular paths of the roller and cam-rib coincide and separate, and thecam is disengaged and through its connection with the rebounds to itsoriginal position to be engaged by the other roller 25. It is thus seenthat owing to the different circular paths followed by the cam androllers, which is due to the relative location of their axes, asdescribed, the roller gradually moves from the axis of the cam-armtoward its outer end,

bent laterally thereby gradually increasing the leverage andcorrespondingly reducing the speed, so that when the plunger approachesthe end of its stroke, where force required to compress is greatest, itmoves slowly and is forced to its work under increased leverage. Duringthe back-and-forth movement of the drawrod it lies closely against theupper side of the coupling-beam, and thus offers no obstruction to thetravel of the draft-animals.

In order to insure a prompt and quick rebound of the plunger to providefor the return of the cam-arm to its original position at rest beforebeing engaged by the advancing roller, so as to prevent the shock of therebound being transmitted to the animals through the roller-arm, Iprovide two springs '2, connected at their rear ends tothe sides of thebolster 2 and at their forward ends'to arms 34, fixed to the ends of therock-shaft 21. The arrangementof thearmsand springs is such that as theplunger is moved to press the charge the springs will be extended undertension, and on the disengagement of the cam by the rollers the springswill, in resuming their normal condition, act throughthe arms 34,rocking lever 18, and link 22 to return the draw-rod instantly to theposition shown in Fig. 2, thereby avoiding any liability of its strikingthe advancing roller.

In order to fold in any loose material which may be drawn in over thetop of the plunger, I provide a folder 35, consisting of a plate mountedat its upper end on a horizontal axis at the rear end of the opening inthe top of the trunk. The axis of this plate is extended outward at itsends and provided with downwardly-extended arms 36, acted on by springs37, connected at their ends to the sides of the bolster. These arms andsprings are so arranged that the folder-plate will be held yieldingly ina downwardly and rearwardly inclined position, as shown in Fig. 4, thesprings permitting the plunger to pass beneath it, as shown in Fig. 6.In order to vary the tension of the springs to meet the conditionsencountered in practice, I provide for, the attachment of the springs atdifferent points in the arms by providing the latter with holes 38. Byconnecting the springs near to or farther from the axis their action onthe folder may be increased or diminished.

The manner of connecting link 22 to the beam 20 of the rocking lever isof importance, it being observed that the end of the arm is and recessedto form two ears 20 and 20, the end of the link being pivoted betweenthese cars. This arrangement admits of the link extending parallel tothe arm 20 and alongside the same when the parts are in the positionrepresented in Fig. 3.

Having thus described my invention, what I claim is- 1. In abaling-press, the combination with a baling-trunk, of a plunger therein,an an gular lever mounted to rock on a horizontal axis below the bottomof the plunger, said lever IIO ' a baling-trunk, of a reciprocatingplunger therein, an angular rocking lever mounted on a horizontal axisbelow the bottom of the plunger, and comprising front and rear arms, alink having its rear end connected to the front arm of the lever and itsother end connected to the plunger forward of its axis, a powermechanism forward of the press,a drawrod operated thereby and extendingrearward, and a link connecting the rear end of the draw-rod with therear arm of the lever.

3. In a baling-press the combination with a baling-trunk, of areciprocating plunger therein, an angular rocking lever comprising afront arm 19 and a rear. arm 20, the former extending laterally at itsend opposite the front arm a link connected at its rear end to the frontarm 19 and at its opposite end to the plunger, a power mechanism forwardof the press, a draw-rod operated thereby and extending rearward, and alink connecting the draw-rod with the laterally-extending end of arm 20.

4. In a baling-press, the combination with a baling-trunk, of a plungertherein having a front pressure-face and a top and side walls, anangular rocking lever mounted on a horizontal axis below the bottom ofthe plunger and comprising front and rear arms extending upward into theplunger beneath the top wall and between the side walls when the plungeris retracted, a link having its rear end connected with the front arm ofthe lever and its other end connected with the front end of the plungerforward of the axis of the lever, a power mechanism forward of thepress, 'a draw-rod extending rearward therefrom, and a link connectingthe rear end of the draw-rod with the rear arm of the lever.

In testimony whereof I hereunto set my hand, this 26th day of April,1898, in the presence of two attesting witnesses. JOHN HEASTON.
